Locum rates are not a single national number. They move with supply, notice and what the shift actually asks of you. Understanding the drivers makes it much easier to judge an offer quickly.
The drivers, roughly in order of impact
Notice. The single biggest factor. A shift posted three weeks out and a shift posted at 7am the same morning are different products. Short notice carries a premium because the pharmacy's alternative is reduced service or closure.
Geography. Rates are driven by how many registered pharmacists are within a sensible travel radius, not by whether an area is expensive to live in. Rural and coastal branches often pay above large-city rates for exactly this reason, which surprises people who expect the London pattern.
Day and date. Weekends, bank holidays and the days either side of them price higher. So does the week between Christmas and New Year.
What the shift involves. A single-handed branch with a high services load, a busy CD safe and no second checker asks more of you than a two-pharmacist branch with an ACT. Rates do not always reflect that difference — which is why reading the posting matters.
Contract type. Whether you are engaged directly or through an agency changes what the pharmacy pays, and sometimes what you receive. Those are two different numbers.
Judging an offer
Ask four questions before accepting:
1. What are the actual hours, including any unpaid break, and what time does the branch close to the public versus when you can leave? 2. Is there a second checker or ACT? This changes the working day more than most rate differences do. 3. What services are running that day, and are you expected to deliver them? 4. What is the travel and parking reality? An hour each way on an unpaid basis is a real reduction in your effective rate.
Effective rate, not headline rate
The number worth comparing is what you keep per hour *away from home*:
Effective rate = (shift fee − travel cost) ÷ (shift hours + travel hours)
A £40/hr shift 70 minutes away and a £34/hr shift ten minutes away are much closer than they look, and sometimes the closer one wins outright.
Negotiating without souring things
Rate conversations go better when they are specific and early. "I can do Saturday, and for a single-handed day at short notice my rate is X" is easier to say yes or no to than a general request for more. If a pharmacy cannot move on rate, ask whether they can move on hours, a guaranteed finish time, or a block booking — those are often easier for them to give and worth real money to you.
Where rates are heading
Be sceptical of anyone claiming to know. Rates respond to workforce supply, the funding settlement and service commissioning, all of which move. What holds is the structure: notice, geography, day, and what the shift asks of you.
The most reliable way to improve your own rate over a year is not negotiation on any single shift — it is becoming the person a handful of branches call first. See getting rebooked, or join free and set your availability.
